Answer 2

This is a question from a test on mathematics for 2nd grade students on the topic of numerical expressions. The question asks to write the value of each product when the letter a is encrypted by some number. The answer is as follows:

- a · 0 = 0, because any number multiplied by zero is zero. - 1 · a = a, because any number multiplied by one is itself.

Therefore, the value of each product depends on the value of a, which is unknown. However, we can use the properties of multiplication to simplify the expressions.
